LAURITS OLUF LARSEN, OF PERTH AMBOY, NEW JERSEY.

LIFE-BOAT.

To all whom it may concern Be it known that I, LAURITS OLUr LARSEN, acitizen of Denmark, residing at Perth Amboy, in the county of Middlesexand State of New Jersey, have invented certain new and usefulImprovements in Life-Boats, of which the following is a specification.

This invention relates to improvements in collapsible life boats and itsobject is to produce a boat of this class that is readily assembled andlocked in operative position and as readily collapsed; lightness,durability and cheapness of manufacture are other objects.

The boat comprises a plurality of longitudinal ribs terminally hinged tothe keel and connected by a canvas covering. and transverse ribs adaptedto retain the longitudinal ribs in assembled position.

The invention consists in the combination and arrangement of parts to behereinafter fully described in the following specification, pointed outin the claims and illustrated in the accompanying drawings which form apart of the specification and in which Figure 1 is a plan of my boat inassembled position. Fig. 2 is a side elevation of the boat collapsed.Fig. 3 is a longitudinal section taken on line 3-8 of Fig. 1. Fig. 4: isa transverse section taken on line 4.4; of Fig- 1. Fig. 5 is a sectiontaken on line 4-4 of Fig. 1 after the boat has been collapsed.

Fig. 6 is a detail of the end of a cross rib in side elevation showingthe fastening device employed. Fig. 7 is a plan of Fig. 6. Fig. 8 is asection taken on line 88 of Fig. 9. Fig. 9 is a detail plan of a portionof a longitudinal rib showing its connection with the cross rib and thefastening means for the two.

Like reference characters indicate corresponding parts throughout theseveral views.

My boat comprises a keel 1 and to the extremities of the same theextremities of outer longitudinal ribs 2, 2 are hinged as at 3, 3.Intermediate longitudinal ribs 4, 4 shorter than the outer ribs are alsohinged to the keel 1 bet-ween its extremities as at 5, 5. Sec ondaryintermediate ribs 6, 6 shorter than the intermediate ribs 4, 4: are alsoterminally hinged to the keel as at 7, 7 and inner longitudinal ribs 8,8 are hinged to the keel as at 9, 9. The bases of the severallongitudinal Specification of Letters Patent.

ribs are covered with a continuous canvas covering 10 which when theribs are extended and in operative position is drawn taut and when theribs are in inoperative position, as shown in Fig. 5, hangs in folds asshown.

When in assembled position the longitudinal ribs are kept in placethrough the medium of a plurality of transverse ribs 11. The ends ofthese ribs pass through the outer longitudinal ribs and are reduced asat 12 and apertured to receive the end 13 of an angular pin 14 providedwith a knob 15 and held in operative position by a spring 16 secured tothe longitudinal rib. The body of the cross rib is notched to engage theseveral longitudinal ribs between the outer longitudinal ribs are drawnaway from the keel laterally as far as the hinges will permit and thecross ribs then placed in position to hold said longitudinal ribsoperative. A canvas top may be secured to the outer longitudinal ribs ifdesired.

What is claimed is 1. In a collapsible life boat comprising longitudinalribs and cross ribs adapted to interlock therewith, friction fingerscarried by said longitudinal ribs for releasable engagement with saidcross ribs, pins carried by said longitudinal ribs for releasableengagement with the terminations of said cross ribs and yieldablelocking means carried by said longitudinal ribs for engagement with saidpins to retain them in operative position.

2. In a collapsible life boat comprising longitudinal ribs and crossribs adapted to interlock therewith, friction fingers carried by saidlongitudinal ribs for releasable engagement with said cross ribs, pinscarried by said longitudinal ribs for releasable engagement with theterminations of said cross ribs, flexible locking means carried by saidlongitudinal ribs for engagement With said pins to normally retain themin operative position and handles for said pins whereby the saidflexible locking means may 5 be thrown out of operative position topermit the collapse of the boat.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two subscribing Witnesses.
